2008-02-01ide-cd: remove needless zeroing of 'info' fields from ide_cdrom_setup()Bartlomiej Zolnierkiewicz

2008-01-28blk_end_request: changing ide-cd (take 4)Kiyoshi Ueda
This patch converts ide-cd (cdrom_newpc_intr()) to use blk_end_request interfaces. Related 'uptodate' arguments are converted to 'error'. In PIO mode, ide-cd (cdrom_newpc_intr()) needs to defer end_that_request_last() until the device clears DRQ_STAT and raises an interrupt after end_that_request_first(). So blk_end_request() has to return without completing request even if no leftover in the request. ide-cd uses blk_end_request_callback() and a dummy callback function, which just returns value '1', to tell blk_end_request_callback() about that.

2008-01-28blk_end_request: changing ide normal caller (take 4)Kiyoshi Ueda
This patch converts "normal" parts of ide to use blk_end_request interfaces. Related 'uptodate' arguments are converted to 'error'. The conversion of 'uptodate' to 'error' is done only for the internal function, __ide_end_request(). ide_end_request() was not changed since it's exported and used by many ide drivers. With this patch, blkdev_dequeue_request() in __ide_end_request() is moved to blk_end_request, since blk_end_request takes care of dequeueing request like below: if (!list_empty(&rq->queuelist)) blkdev_dequeue_request(rq); In the case of ide, o 'dequeue' variable of __ide_end_request() is 1 only when the request is still linked to the queue (i.e. rq->queuelist is not empty) o 'dequeue' variable of __ide_end_request() is 0 only when the request has already been removed from the queue (i.e. rq->queuelist is empty) So blk_end_request can handle it correctly although ide always run thought the code above.

2007-12-12ide-cd: remove dead post_transform_command()Bartlomiej Zolnierkiewicz
post_transform_command() call in cdrom_newpc_intr() has no effect because it is done after the request has already been fully completed (rq->bio and rq->data are always NULL). It was verified to be true regardless whether INQUIRY command is using DMA or PIO to transfer data (by using modified Tejun Heo's test-shortsg.c utility and adding a few printk()-s to ide-cd). This was uncovered thanks to the "blk_end_request: full I/O completion handler (take 3)" patch series from Kiyoshi Ueda.

2007-12-12ide: DMA reporting and validity checking fixes (take 3)Bartlomiej Zolnierkiewicz
* ide_xfer_verbose() fixups: - beautify returned mode names - fix PIO5 reporting - make it return 'const char *' * Change printk() level from KERN_DEBUG to KERN_INFO in ide_find_dma_mode(). * Add ide_id_dma_bug() helper based on ide_dma_verbose() to check for invalid DMA info in identify block. * Use ide_id_dma_bug() in ide_tune_dma() and ide_driveid_update(). As a result DMA won't be tuned or will be disabled after tuning if device reports inconsistent info about enabled DMA mode (ide_dma_verbose() does the same checks while the IDE device is probed by ide-{cd,disk} device driver). * Remove no longer needed ide_dma_verbose(). This patch should fix the following problem with out-of-sync IDE messages reported by Nick Warne: hdd: ATAPI 48X DVD-ROM DVD-R-RAM CD-R/RW drive, 2048kB Cache<7>hdd: skipping word 93 validity check , UDMA(66) and later debugged by Mark Lord to be caused by: ide_dma_verbose() printk( ... "2048kB Cache"); eighty_ninty_three() printk(KERN_DEBUG "%s: skipping word 93 validity check\n"); ide_dma_verbose() printk(", UDMA(66)" Please note that as a result ide-{cd,disk} device drivers won't report the DMA speed used but this is intended since now DMA mode being used is always reported by IDE core code. v2: * fixes suggested by Randy: - use KERN_CONT for printk()-s in ide-{cd,disk}.c - don't remove argument name from ide_xfer_verbose() declaration v3: * Remove incorrect check for (id->field_valid & 1) from ide_id_dma_bug() (spotted by Sergei). * "XFER SLOW" -> "PIO SLOW" in ide_xfer_verbose() (suggested by Sergei). * Fix ide_find_dma_mode() to report the correct mode ('mode' after being limited by 'req_mode').

2007-04-10ide: ugly messages trying to open CD drive with no media presentStuart Hayes
I get the following error messages when trying to open a CD device (specifically, the Teac CD-ROM CD-224E) that has no media present: hda: packet command error: status=3D0x51 { DriveReady SeekComplete Error } hda: packet command error: error=3D0x54 { AbortedCommand LastFailedSense=0x05 } ide: failed opcode was: unknown This happens when a "start stop unit" command (0x1b 0 0 0 3 0 0 0 0 0) is sent to the drive to try to close the CD-ROM tray, but this drive doesn't have that capability (it's a slim portable-type CD-ROM), so it reports sense key 5 (illegal request) with asc/ascq 24/0. This is exactly how SFF8090i says it should respond. But ide-cd.c (in cdrom_decode_status() ) just sees sense key 5 and spews out an error. It then goes on to request sense data, and cdrom_log_sense() understands this error and doesn't log it. The patch, for kernel 2.6.20.4, suppresses this error message.
